Probs with accessing variables in yaml file

Hi,

i have a script that is configured via yaml file :

—script-----------

require ‘yaml’
require ‘highline/import’
require ‘win32/registry’

config=YAML.load_file(“cvs_login.yaml”)

[ … ]

def filesed!(pattern, replaceString, filename)
regexPattern = Regexp.compile(pattern)
tmpFilename = “#{filename}.#{Time.now.usec}”
tmpFile = File.new(tmpFilename, “w”)
srcFile = File.open(filename)
srcFile.each_line do |line|
tmpFile.print line.gsub(regexPattern) {|match|
replaceString
}
end
tmpFile.close
srcFile .close
File.rename(tmpFilename, filename)
end

if config[‘targetdirs’]

Win32::Registry::HKEY_CURRENT_USER.open(‘Software\Cvsnt\cvspass’) do
|reg|
@cvsreg =
reg[":pserver:#{ENV[“USERNAME”]}@cvsprod:d:/cvsrepos/test"]
end

config[‘targetdirs’].each do |dir|
Dir.chdir(dir)
puts “\n\n”
Dir.glob(config[‘targetfilepattern’]).each do |file|
puts “… processing “<<File.expand_path(”#{file}”)
puts ‘bla’<<@cvsreg
puts 'replaceto == '<<config[‘replaceto’]

#filesed!(".*</Passwort>","</Pa
sswort>","#{file}")
filesed!(config[‘replacefrom’],config[‘replaceto’],"#{file}")
end
end
puts “\n\nDone !!”
sleep 1
else
puts “\n\nDone !!”
sleep 1
end

—script-----------

–yaml-------------

cvs_login.yaml looks like =

targetdirs:

  • Y:/tempwork

targetfilepattern: “Scm*.xml”

replacefrom: “.*</Passwort>”
replaceto: “<![CDATA[#{@cvsreg}]></Passwort>”

–yaml--------------

Question =

If i write :
puts 'replaceto == '<<"</Passwort>"
direct into the script it’s echoed correct, but it doesn’t work via yaml
file;
when running via yaml the line in my xml file get’s replaced to =

<![CDATA[#{@cvsreg}]></Passwort>

Where’s the failure ??

Hi,

don’t know if there’s another | better way, but
i solved it like that =

yaml has now =

replaceto1: “<![CDATA[”
replaceto2: “]>”

and my script has =

s=config[‘replaceto1’]<<"#{@cvsreg}"<<config[‘replaceto2’]
[…]
filesed!(config[‘replacefrom’],s,"#{file}")

Hi,

the #{} are evaluated when the string is instantiated, i.e. in normal
case when the line containing the literal (note: the LITERAL) is
evaluated. When you load the string from yaml, these #{} are not
evaluated at all.

What you might want to do is to add quotes around and call eval –
e.g. config[‘replaceto’] = eval(""#{config[‘replaceto’]}""), with
all the dangerous implications of eval. (Note the double use of #{}…
once it is evaluated as the line is parsed to create another literal
that is then passed to eval to expand again. I could have avoided the
outer expansion by using “”" + config[…] + “”", but I guess this
one’s faster), and it’s shorter in any case.)
